I don't "do" any holidays, so no stress/triggering from that angle, but 4th of July, well... I like a good show as much as the next person -- visually, not sound-wise (though I don't go), but people setting them off in neighborhoods -- especially at random non-4th times, ugh! Hypervigilence is an issue for me so I spend about 2 weeks every year jumping a mile every time one goes off. Not a fan.
